everything inspires us. Even when i just go and brush my teeth and get up with an idea of a toon toothbrush or something... but i don't think that we will focus on other games than toonstruck 1 when creating the sequel ^^

Why not, these games may suggest ideas as well (inspiration of course, not ripoff). For example, CMI shares some general similarities with Toonstruck, and Full Throttle can suggest something about high technologies and Wild West.
